THA 750×6 S31603 Torispherical Dished Head, manufactured by Henan Guojiang Precision Formed Head. As a benchmark enterprise in China's precision pressure vessel component industry, Henan Guojiang has specialised in the R&D, production, and customisation of torispherical dished heads for over 12 years, with profound technical accumulation.

• Inner Diameter: 750mm - Specifically designed for small and medium-sized pressure vessels in chemical, pharmaceutical, food processing and other industries, with strong adaptability
• Nominal Thickness: 6mm - Optimised for working pressure range of 0.1MPa-60MPa, resistant to medium-strong corrosive and non-corrosive media
• Material: S31603 stainless steel - Each batch of products is equipped with a complete Material Test Certificate (MTC) for strong material traceability

Produced by cold forming technology, which maximally retains the original ductility and weldability of S31603 stainless steel. Advanced hydraulic forming equipment ensures compliance with GB/T 25198 and ASME standards, resulting in smooth and uniform surfaces that effectively avoid local stress concentration.

• Inspection Process: 100% full inspection coverage, including Ultrasonic Testing (UT), Penetrant Testing (PT), and 3D laser scanning, to accurately control product precision
• Compliance Standards: Meets GB/T 25198-2023, ASME BPVC Section VIII Division 1, and PED 2014/68/EU directives
• Certifications: ISO 9001:2015, ISO 14001:2015 Quality Management System Certifications, and ASME "U" Stamp approval
